  摘要：

  RuO2/NaIO4 oxidation of N-Boc-4-silyloxy and 4-acetoxy proline methyl esters under ethyl acetate/water biphase condition gave N-Boc-4-silyloxy and 4-acetoxy pyroglutamic acid derivates in high yields. Desilylation with TBAF afforded both cis- and trans-N-Boc-methyl-4-hydroxy pyroglutamates. (C) 2001 DuPont Pharmaceuticals Company. Published by Elsevier Science Ltd. All rights reserved.

  enantiomerically pure diasteroisomers of γ-benzyloxy-S-glutamic acid was performed using trans-4-hydroxy-l-proline as a source of chirality, while the erythro and threo isomers of β-benzyloxy-S-glutamic acid were prepared starting from (R)-Garner's aldehyde. All new derivatives were tested for their inhibitory activity against excitatory amino acid transporters in a rat synaptosomal preparation and their
